Is your feature request related to a problem? Please describe. Very commonly used no-reference metric, which is mentioned in almost all IQA papers after it's initial release in 2013.

Describe the solution you'd like

Implement metric on PyTorch
Verify that it produces the same scores as MATLAB version

Additional context Original paper: https://live.ece.utexas.edu/research/Quality/niqe_spl.pdf Python code: https://github.com/guptapraful/niqe/blob/master/niqe.py

Please note that the linked implementation of the NIQE metric may be erroneous, see this issue.
